Technically, if you +// use a type member of a template class (i.e. a type declared within the +// template class by a local typedef), you need to tell the compiler that it +// is a type name. This is because the compiler cannot work out whether a +// member is a type, a method or a data field at compile time. However, +// support for the typename keyword has traditionally been incomplete in both +// gcc and Visual Studio. I have used macros to try to resolve this issue. The +// macros add the keyword for compiler versions that require it and omit it +// for compiler versions that do not support it + +// There are five places where typename keywords cause problems: +// +// 1) in a typedef where a template class's member type is being mapped onto +// a type definition within another template class or function +// e.g. template fn () { +// typedef typename someclass::member_type local_type; +// ^^^^^^^^ +// 2) in a function parameter declaration, with similar rules to the above +// e.g. template fn (typename someclass::member_type) +// ^^^^^^^^ +// 3) in instantiating a template, the parameter to the template, with similar rules to the above +// e.g. template_class::member_type> +// ^^^^^^^^ +// 4) Return expressions +// e.g. return typename ntree::const_iterator(this,m_root); +// ^^^^^^^^ +// 5) Creating temporary objects when passing arguments to a function or constructor +// e.g. return typename ntree::const_prefix_iterator(typename ntree::const_iterator(this,m_root)); +// ^^^^^^^^ +// Note that the typename keyword is only required when the type being referred to is a member of a template class +// +// So far it *seems* as if all compilers either require all of them or none of +// them, so this set of situations can be handled by a single macro + +// default values, overridden for individual problem cases below +#define TYPENAME typename + +// GCC +// - pre-version 3 didn't handle typename in any of these cases +// - version 3 onwards, typename is required for all three cases as per default +#ifdef __GNUC__ +#if __GNUC__ < 3 +#undef TYPENAME +#define TYPENAME +#endif +#endif + +// Visual Studio +// - version 6 (compiler v.12) cannot handle typename in any of these cases +// - version 7 (.NET) (compiler v.13) requires a typename in a parameter specification but supports all +// - version 8 (2005) (compiler v.14) requires parameters and templates, supports all +#ifdef _MSC_VER +#if _MSC_VER <= 1200 +#undef TYPENAME +#define TYPENAME +#endif +#endif + +// Borland +// - doesn't handle typename in 5.5, does in 5.82, not sure about other cases +#ifdef __BORLANDC__ +#if __BORLANDC__ <= 0x550 +#undef TYPENAME +#define TYPENAME +#endif +#endif + +//////////////////////////////////////////////////////////////////////////////// +// Member templates +// e.g. a template function in a template class + +// Not all compilers support them - this fix can be used to disable member +// templates for compilers that don't.
